Question

A block of mass 8.60 kg is pulled along a horizontal frictionless surface by a cord that exerts a force of 33 N at an angle 29.40 degrees from the horizontal. What is the magnitude of the normal force exerted on the mass by the floor?

I solved for the acceleration, which was 3.34 m/s/s (part one of the question) and I tried solving for Fnormal using Fnorm = mg + Fsintheta but the answer it gave me was incorrect

Answer 1

Fn = Mg-F*sin29.4.
